About the Switch 4500 The Switch 4500 Family are mixed media devices. Table 2 summarizes what each
Switch consists of:
Table 2 Switch 4500 Family Hardware
* Combo SFP and 10/100/1000 Ports
† 1000BASE-T SFP transceiver installed in last two 1000BASE-X SFP ports
The Switch 4500 Family provides workgroup connectivity at 10- and 100-Mbps,
and high-speed Gigabit ports for stacking, uplinks to a backbone, or for server
connections. With stacking, you can add additional Switch 4500s as your network
grows while preserving ease of management.
For information about using the software features of the Switch, refer to the
“Command Reference Guide” on located on 3Com’s Web site at www.3com.com.

WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot be used
as standard traditional telephone sockets, or to connect the unit to a traditi
onal PBX or
public telephone network. Only connect RJ-45 data connectors, network telephony
systems, or network telephones to these sockets.
Either shielded or unshielded data cables with shielded or unshielded jacks can be
connected to these data sockets.
10BASE-T/ 100BASE-TX
Ports
The Switch 4500 has 24 or 48 auto-negotiating 10BASE-T/100BASE-TX ports
configured as Auto MDIX (cross-over). These ports automatically provide the
appropriate connection. Alternatively, you can manually set these ports to
10BASE-T half-duplex, 10BASE-T full0-duplex, 100BASE-TX half-duplex or
100BASE-TX full-duplex. The maximum segment length is 100 m (328 ft) over
Category 5 twisted pair cabl

Gigabit Ports Switch 4500 10/100 Ethernet models support two simultaneous Gigabit
connections. Each switch has four Gigabit ports, arranged in two pairs called

“dual-personality combo port pairs.” Only one port in each pair can be activeat a
time.
The paired ports for the Switch 4500 26 Port and PWR 26 Port are:
25 and 27
26 and 28
The paired ports for the Switch 4500 50 Port and PWR 50 Port are:
49 and 51
50 and 52
By default, the ports are enabled as follows for the 26-Port switches:
Port 25 = active; Port 27 = inactive
Port 26 = active; Port 28 = inactive
By default, the ports are enabled as follows for the 50-Port switches:
Port 49 = active; Port 51 = inactive
Port 50 = active; Port 52 = inactive
To change which port is active, issue the undo shut
down command on the inactive
port. This will enable the previously inactive port and disable its pair. Issuing this
command will cause the switch to reboot.
A Gigabit connection can be either copper
-based 1000Base-T or SFP-based
fiberoptic connection. On the Switch 4500 10/100 26 Port unit, there are two SFP
slots and two 1000Base-T ports. On the Switch 4500 PWR 26 Port, 50 Port, and
PWR 50 Port models all the physical Gigabit ports are SFP slots.
Two 1000Base-T SFP transceivers are included with thes
e units. These SFP
transceivers can be inserted in any of the four SFP slots to provide copper Gigabit
connectivity. If you install these in the inactive ports, then you will need to issue
the undo shutdown command on those ports to make them active.
SFP (Small Form Factor Pluggable, or mini-GB
IC) p
orts support fiber Gigabit
Ethernet short-wave (SX), long-wave (LX), long-haul (LH70) and copper (T) SFP
Transceivers in any combination. This offers you the flexibility of using SFP
transceivers to provide connectivity between the Switch and remote 1000 Mbps
workgroups.
The default state for these ports is auto-negotiation enabled, where the speed,
d
uplex and flow control modes are negotiated. As the speed and duplex modes
are fixed by the media type, only the flow control is negotiated with the link
partner. Alternatively, auto-negotiation can be disabled (except 1000BASE-T which
auto-negotiation is mandatory) and the flow control setting can be manually
configured.
Console Port The console port allows you to connect a ter
min
al and perform remote or local
out-of-band management. As the console port on the Switch is an RJ-45 port, you
16 CHAPTER 1: INTRODUCING THE SWITCH 4500 FAMILY
will need to connect an RJ-45 to DB9 converter cable to a standard null modem
cable in order to connect a terminal.

Unit LED The Unit LED is a seven segment display visible on the front of the Switch. The Unit
LED can be used to indicate the unit number in a fabric, POST test ID and software
upgrade information. In the unlikely event of a hardware fault occurring, the Unit
LED may be used to help diagnose the problem. For information on using the Unit
LED for problem solving, see “Solving Problems Indicated by LEDs” on page 52
